Hi,I am trying to use a STEVAL_PCC009V2 board connected to a EVAL6474H board to drive a stepper motor.When I run the SPIN eval software I get a notice that the firmware is not the latest and I need to update it. I just ordered the board, but it shows...

I am looking at using the L6474 to drive a stepper motor. I have a question about the absolute position register (ABS_POS).It says it is the current motor absolute position, but I want to clarify that it really is just a counter for the number of ste...

I'm trying to init the EEPROM.. the code is returning HAL_FLASH_ERROR_SIZ from within FLASH_WaitForLastOperation.. I haven't really found much info about this error code, other than it is a size error... How do I fix it? I believe this used to work ...

I'm having the same issue... Did you figure out a solution?

In case anyone else runs into this.. there were a few things going on.First, there apparently is an issue with the pre-built binaries that come with azure fp. If you open the project and do your own build it works OK.Second, It matters where you ar...

Digging into it more, when using just the url, it fails in tlsio_mbedtls_Stm32Cube_Nucleo.c, line 575, if (tls_io_instance->tlsio_state != TLSIO_STATE_OPEN)The tlsio_state is TLSIO_STATE_NOT_OPEN.It looks like it is failing the handshake here because...

Erasing the chip through ST-Link Utility seems fine.

The sensor is directly input to the eval board.. it's certainly possible the eval board can't handle it, but since there is nothing I can do about that, I'm looking at it from a configuration and software side.
